Other Liabilities, Long-term	Other Liabilities, Long-term In September 2019, Legacy Origin entered into a $5.0 million prepayment agreement with a counterparty for the purchase of products from Origin 1. The prepayment is to be made in two equal installments: the first $2.5 million was paid in October 2019 and the remaining $2.5 million is due within 30 days of the customer confirming that a sample from Origin 1 meets the customer’s specifications. The Company and customer agreed to work in good faith to execute an Offtake Agreement, the agreed terms of which are set forth in the prepayment agreement, whereby 100% of the prepayment will be applied against future purchases. The prepayment agreement provides the customer a capacity reservation of up to a specified annual volume of product from Origin 1 for a term of ten years, pursuant to the terms of an Offtake Agreement. At December 31, 2023 and 2022, the total amount outstanding on this agreement was $2.5 million. On February 5, 2024, the parties entered into a memorandum of understanding by which they agreed that the counterparty would be released from its obligation to pay the remaining $2.5 million of the prepayment and that Legacy Origin would refund the first $2.5 million within a certain period after reporting in its Quarterly Report on Form 10-Q that its cash on hand has crossed a specified threshold. Legacy Origin received a $5.0 million prepayment from a customer for product from Origin 1 pursuant to an Offtake Agreement entered into in November 2016. The agreement was amended in 2019 and added the accrued interest of $0.1 million to the principal balance. As a result, the aggregate principal amount became $5.1 million. The prepayment was to be credited against the purchase of products from Origin 1 over the term of the Offtake Agreement, specifically, by applying a credit to product purchases each month over the first five years of operation of Origin 1 up to $7.5 million, which is equal to 150% of the prepayment amount. If product purchases were not sufficient to recover the advances, the application of the credit to purchases as payment of the advances would continue until fully repaid. The prepayment is secured by an agreement that was to be repaid in cash in the event the prepayment cannot be credited against the purchase of product, for example, if Origin 1 were never constructed. The agreement is collateralized substantially by Origin 1 and other assets of Origin Materials Canada Pioneer Limited. If repaid in cash, the agreement bears an annual interest rate of the three-month Secured Overnight Financing Rate (“SOFR”) plus 0.25% (5.61% at December 31, 2023) and matures five years from the commercial operation date of Origin 1, which is defined by the plant’s actual production of a certain volume of product as well as its capacity to produce a certain annual volume of product. In February 2024, Legacy Origin and the customer amended the agreement to provide for repayment in three installments consisting of approximately $2.2 million on March 1, 2024, $1.6 million on September 1, 2024, and $2.1 million on March 1, 2025 instead of applying a credit to product purchases under the Offtake Agreement. At December 31, 2023 and 2022, the total amount outstanding was $5.1 million and accrued interest outstanding was $0.6 million and $0.3 million, respectively.
